LM340: High accuracy LDO consult

Part Number: LM340

Hi team,

My customer want to use high accuracy LDO, output accuracy target 1%. I find we only have 2% LDO, such as LM340. Do we have any other option here? 

One more question here, can TI LDO get 0.5% accuracy? What limit the output voltage accuracy? Thanks.

BR,

CL

    Hi Charles,

    Our LM317A has a 1% output accuracy.  However, when using an adjustable regulator, for the total accuracy picture, you need to consider the accuracy of the resistors used to set VOUT. 

    For this, we have the TPS7A47 which has a nominal accuracy of 1% and uses our Any-Out feature which allows you to dynamically set VOUT without external resistors., 

    I hope this answers your question.
